      Interesting thread. Between my design and Kent's design there have been hundreds of these filters built. Most if not all working Perfectly. Innovation and new ideas can be nice but as Jeff said there's no real nead to deviate from a tried and proven design. If it ain't broke, don't try to fix it

      OR

      KISS!.

      Hey. No harm in trying to make a better mousetrap !!!

      So quick question ... I have one bulkhead that I’m using. It’s basicallt the same as the shower drain I also am using. For the bulkhead... do I need to remove the rubber gasket and use marine sealer ?

      So I finally got my S&G filter up and running this past weekend… and I am amazed on how it’s worked out. I went from seeing less then a foot down.. to completely clear to the bottom just overnight. (I now see how many river rocks my son has “accidentally” dropped into the pond… a drill bit… and a small PVC piece.) I had put off the cleaning of my other filter while building this S&G filter so the water was bit worse then normal. Anyway…I still need to add some “trim” to hide the pipes under the barrel and then stain it all…. But I am very happy with the results so far. Just some random thoughts along the way…

      - I must of run to the hardware store a million times getting parts here and there. It probably would be easier to just buy all the PVC joints at the store.. And then return what you don’t use.

      - SHOWER DRAIN: The 2in shower drain I used for the bottom clean-out line was indicated as PVC …. But after glueing it up with standard PVC glue and then doing a leak check the next day.. The glue failed and I could pull the pipe right out of the drain quite easily. So I then glued it up with PVC to ABS glue which worked as expected. It’s just a gray plastic and indicated as “PVC” by the manufacturer… not ABS… so I was a little confused. But it’s nice and tight now and not going anywhere.

      - BOTTOM GRATE: I cut out a bread rack for the bottom grate in the barrel. The material is nice and ridged… but I was worried the 1” openings were still a bit too big on it, so I cut up a few of those plastic gutter guards things and zip tied them to the grate. They are basically sheets of vinyl with tightly perforated 1/4in holes.. And I just removed the screening that’s glued to them.

      - STONE: The largest stone I purchased in bags for the bottom layer didn’t seem to be sorted quite that well.. Too many small broken pieces that I didn’t want on the bottom… so while dumping them into a wheel barrow to clean them up with the hose… I did a quick sorting to get the smaller stones out (to be used in a higher layer of the barrel). Having a 9 year old helps with the hose and sorting part!

      - OUTLETS: I mistakenly drilled my two outlet holes too high in the barrel. Me no good at math! This puts the opening of the elbows quite hight in the barrel… but it’s worked out so far. Even with it boiling it doesn’t overflow out.

      - AIR MANIFOLD: I left the air manifold line sticking quite high out of the barrel for now. On the first cleanout.. I was hanging close to the barrel and didn’t realize the water comes rushing back into the manifold and will pop out of the top pipe…. Almost got a soaking.

      - NOISE: I did drill in a few air holes to the outside elbow of the outlet. This helps with the sucking sound you get at the top inlet. The loudest noise though is from the water falling down the 3 foot drop before it hits the long sweep elbow... which in my set up has some water in it. I am trying out a fix by taking a bunch of those packing strips… tying them together at one end… folding them up to get a bit of a zig zag in them.. and letting it get pulled into the 3 foot drop area. I am hoping interrupting the fall will reduce the noise a bit. It seems to work a bit… but I need longer strips.

      - PUMP QUESTION: Right now I have my pump choked down a decent amount to not overrun the single barrel. Would it be better to have a Y and ball valve in that offshot line to essentially just return water back to the pond and help with water movement in the pond? I could completely hide this under the bridge before the line goes under the deck towards the filter.

      - FUTURE ADD ON QUESTION: I am already looking into making a trickle tower in a 30 gallon barrel to the right of this one. I would put the media in two stacked egg crates.Trying to find a black barrel might be a pain to find on craigslist though… but my mom always told me to make sure your barrels match! I could essentially seal up the existing outlet.. Make a new one to the side which will feed the TT at the top.. And the just join the outlet to my exiting line. I am seeing I could get a used supply of K1, K2, & K3 mixed together for $30 for 1.4 cubic feet. Do people ever use this in TT? Or would featherrock be better?

      Thanks again for the help! Below is a pick of the deck when i was pulling it apart to run the lines.. and then a few "where I'm at now" pics.

      Next stage to add. Just comparing price on used mixed K1,2,3 vs featherrock.

      Thanks

      So I’m now seeing that a 3” bulkhead is $30... quite the jump from a 2”. Does anyone have either a good source or maybe an alternate fitting at 3” that has a low profile to be used as a bottom drain on a barrel

      It's not the overflowing that's an issue as much as the sand will fluidize and channel at around 2200 gph....in my 4 barrels that's my Max flow, yours may vary but 2- 2.5 k is Max I believe..

      Is this thread going in circles, or was that another SG thread(?) because 3" electrical male/female threaded conduit connections are always mentioned early on. As others have said, just stick to the recommended parts and design and get on with things. "Perfect is the enemy of good enough."

      Sorry... I didn’t mention a segway to my building of secondary barrel that I’ll do a trickle down filter with. So I was looking for something with a lower profile then the electric conduit since it is going to be at the bottom of the barrel draining out.
